Abstract
The utility model discloses an auxiliary return oilway for engine oil of cylinder cap, which relates to a engine cylinder cap, which has an upper surface and a lower surface that is connected with cylinder body closely, the top surface of said cylinder cap is provided with a pit, said cylinder cap is also provided with a cylinder cap oilway communicating the pit and the lower surface of the cylinder cap, the cylinder cap is communicated with a return oilway on cylinder body. The utility model relates to a supplementary return oil mode for return oil through rod hole, effective solves thorough return oil on original cylinder cap only through rod hole, thereby the engine oil could return to oil sump under any driving condition.
Description
Technical field
The utility model relates to a kind of technical field of motor, especially relates to a kind of auxiliary oil return oil duct of cylinder head machine oil that can be used for the machine oil oil return on the motor.
Background technique
The machine oil oil return that engine cylinder covers is one important step that guarantees normal working of engine, and current machine oil oil return mode commonly used on motor is that the oil duct of getting back on the cylinder body from the push-rod hole that is provided with returns in the oil sump.But owing to above engine cylinder cap, be furnished with other engine component, therefore on the cylinder head of motor, just might retain organic oil, make motor when tilting, cause the oil return of machine oil from push-rod hole not smooth at some position.
Summary of the invention
The technical problems to be solved in the utility model has provided the auxiliary oil return oil duct of a kind of cylinder head machine oil, it has effectively solved former cylinder and has covered and only depend on the halfway phenomenon of push-rod hole oil return, make vehicle no matter under what kind of walk, machine oil can be got back in the oil sump.
For solving the problems of the technologies described above, the technical solution of the utility model is: cylinder head machine oil is assisted the oil return oil duct, relate to engine cylinder cap, cylinder head have upper surface and can with the close-connected lower surface of cylinder body, the upper surface of described cylinder head is provided with pit, also is provided with on the described cylinder head to be communicated with pit and the lower surface of cylinder head and the cylinder cap oil duct that can be communicated with the oil return oil duct on the cylinder body.
Adopt the auxiliary oil return oil duct of cylinder head machine oil of said structure, owing to be to adopt to be provided with the pit that is communicated with on the cylinder head and the cylinder cap oil duct of the oil return oil duct on the cylinder body on the cylinder head of motor, like this, oil on the engine cylinder cap is injected in the pit, in the oil return oil duct finally flow back into the oil sump of motor, realize that cylinder covers an additional oil return mode to the push-rod hole oil return, effectively having solved former cylinder covers and only depends on the halfway phenomenon of push-rod hole oil return, make vehicle no matter under what kind of walk, machine oil can be got back in the oil sump.
Description of drawings
Below in conjunction with accompanying drawing embodiment of the present utility model is further described:
Fig. 1 is the cylinder head plan view of the auxiliary oil return oil duct of cylinder head machine oil of the present utility model;
Fig. 2 is the A---A sectional view of Fig. 1.
Embodiment
See figures.1.and.2, the auxiliary oil return oil duct of a kind of cylinder head machine oil of the present utility model is: it relates to engine cylinder cap 1, cylinder head 1 have upper surface 12 and can with the close-connected lower surface 11 of cylinder body, on the upper surface 12 of cylinder head 1, be provided with pit 2, this pit 2 can be to give the casting pit that stays when the manufacturing cylinder head, also can be after cylinder head 1 processing, to process again, on cylinder head 1, be provided with cylinder cap oil duct 3, cylinder cap oil duct 3 is communicated with the lower surface 11 of pit 2 and cylinder head 1, and can be communicated with the oil return oil duct on the cylinder body, like this, with this cylinder head machine oil auxiliary oil return oil duct be applied to motor cylinder head on the time, no matter be that vehicle is under what kind of walk, machine oil can be pooled in the pit 2, be communicated with by cylinder cap oil duct 3 with oil duct on the cylinder body that cylinder cap oil duct 3 is communicated with again, thereby realization is with the purpose of machine oil Hui Yang in the oil sump.
